...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through tonight.

...Synopsis...
A mid-level shortwave trough over the western Great Lakes will
continue to quickly move east through the afternoon and a lingering
thunderstorm cluster over west-central IL late this morning will
gradually diminish as this disturbance becomes displaced.

Farther south, isolated to widely scattered thunderstorms will be
possible from parts of the Mid-Atlantic southwestward to the Gulf
Coast/Southeast. Weak flow will limit storm intensity in these
regions. A vigorous shortwave trough will move across the Pacific
Northwest and northern Rockies/Plains through tonight. While
large-scale forcing and mid-level flow associated with the upper
trough passage will be strong, thunderstorm coverage is expected to
remain sparse due to a rather dry airmass present across these
areas.
